Designing Atomically Precise and Robust Covalent Organic Frameworks for Enhanced Iodine/Iodate Uptake：Structures with and without Phenol Hydroxy Groups

Key Points

• The central aim is to design effective adsorbents for the removal of iodine and iodate from the environment.
• Developed covalent organic frameworks (COFs) with varying structures.
• Compared frameworks containing phenol hydroxy groups to those without.
• Evaluated adsorbent efficiency through controlled absorption tests.
• COFs with phenol hydroxy groups showed significantly higher iodine uptake than those without.
• Enhanced structural stability was observed in the developed frameworks.
• Adsorption efficiency indicates potential for practical environmental applications.
